Hi. I need your help :) I plan to include Ajax queries into component, ie dynamic loading data. For example, there is no need to load all placemarks (as I do now). And for example you have list of something, click on its item cause load data. And my question: List of what. Because placemarks can be in different maps, and may be you want to load in this case. - list of categories (all, used on this map, plain, hierarchy) - list of placemark groups - ... And is it convenient to have one big text item, where you will enter its IDs, or would be more useful to use tables (lists) Please, don't hesitate. Post me. And explain how want you use it - it is for usability.
